I had a rush 'its got to be done before Christmas' job and needed a large metalclad board. As i am away next week i got a 16 way Contactum fully loaded with Rcbo's. I have no problems with the quality of Contactum gear but never again !!!. With the Rcbo's fitted there is less than 30mm between the top of the breakers and the N & E terminals. Imagine that in a 16 way board which was a upgrade from a 6 way with loads of crimps. If its not too embarrassing i may take a pic tomorrow and post it.
On the other hand Wylex metalclad have to be the best at the moment. They have moved the the breakers down so there's no huge gap under the busbar which is never used, and loads of space at the top even with Rcbo's
